Previously, running git crrev-parse {crrev_number} on Mac doesn't
produce any meaningful output, and the reason is that parameter
substitutions resulted in extra back slashes ('\'):
ref="refs/heads/master"
remote_ref="${ref/refs\/heads/refs\/remotes\/origin}"
expected: remote_ref="refs/remotes/origin/master"
actual: remote_ref="refs\/remotes\/origin/master"
This CL fixes the issue by removing the extra back slashes.

# This git extension converts a chromium commit number to its git commit hash.
|
|
# It accepts the following input formats:
|
|
#
|
|
# $ git crrev-parse Cr-Commit-Position: refs/heads/master@{#311769}
|
|
# $ git crrev-parse ' Cr-Commit-Position: refs/heads/master@{#311769}'
|
|
# $ git crrev-parse 'Cr-Commit-Position: refs/heads/master@{#311769}'
|
|
# $ git crrev-parse refs/heads/master@{#311769}
|
|
#
|
|
# It also works for branches (assuming you have branches in your local
|
|
# checkout):
|
|
#
|
|
# $ git crrev-parse refs/branch-heads/2278@{#2}
|
|
#
|
|
# If you don't specify a branch, refs/heads/master is assumed:
|
|
#
|
|
# $ git crrev-parse @{#311769}
|
|
# $ git crrev-parse 311769
|
|
|
|
# Developer note: this script makes heavy use of prefix/suffix/pattern
|
|
# substitution for bash variables. Refer to the "Parameter Expansion"
|
|
# section of the man page for bash.
